Cheers Colyn!
So here's some progress from the last couple of evenings. Firstly here is the finished air tank mounting:
Like I said the IEF bumper was HARD - actually unbelievably so. We got serious on Thursday night, tired of small drills and tired of doing everything with a little CFL camping light, so we broke out the big guns

A massive mercury lamp to make everything like daylight (why the hell didn't I remember this thing was in the factory earlier?) and a big magnetic drill press which made the going a whole lot easier:
It was still pretty fiddly as we couldn't really get a 100% solid seating for the magnetic base, so it took Cobby holding and me drilling... A bit like the safe cracking scenes in numerous movies only no safety goggles and no gold - our only goal was a hole!
Finished!
And the final result after welding the nuts so there is little chance (unless someone is really tooled up) of opening the back. Obviously this is not the sort of thing where I would lock it constantly - only if leaving the vehicle for a longer time somewhere a bit sketchy.
As I said, the solar panel is mounted:
This afternoon I stripped down the factory snorkel for two reasons:
- to run the wires down it for the solar panel (they then come out a hole in the wing, before the airfilter housing)
- To silicone all the joints as the factory snorkel is not waterproof. With my track record on this it is better safe than sorry.
I learned the vessel is next Sunday so It's not as hectic as it might have been.
